I bought this shoe per suggestion from a fellow free runner and use them as my main shoe for the sport. They are absolutely incredible on brick and concrete as I can actually find myself literally sticking to surfaces! They have great support and are incredibly comfortable. However, they are not the prettiest shoe on the market they sure do get the job done. Also, outside of concrete they do slip around a bit. Especially on tile, indoor surfaces, and railings (metal). The stealth rubber actually gets even stickier the more you wear them so I'm sure this behavior will die down. For free runner/parkour artists, these are a must buy.

I've been free running and into parkour for several years now and jumped at the opportunity to experience a shoe designed specifically for my physically demanding hobby. Upon receiving my 5.10's I was floored by the traction quality and comfortability of wear. The funny thing about the free runner is that, while it was designed for grip, traction and stability, it is unfortunately heavy, and while the weight isn't enough to make the shoe unusable, it is enough to hold it back from perfection. At times it feels as though the free runner is a hinderance to the fluidity inherent in parkour and free running instead of a perfect compliment. It's for this reason that I switch my shoes every few trips, to allow myself to experience the perks of different free running footwear.
